FamiTracker 0.4.6 and 0.5 beta 5 work in Wine on a PC with an x86 (or x86-64) CPU and X Window System. But this doesn't include the Raspberry Pi line of single-board computers or other devices with an ARM CPU.

Winelib allows compiling Wine-compatible Windows applications for Linux and *BSD on non-x86 CPU architectures. In theory, this would let you bring up FamiTracker on a Raspberry Pi, as an alternative to using Qt. Would this be a worthwhile goal?
